what temperature is this light? Is it for vegetative or fruit/flowering state? I am looking for 6500k

Light is 6400k. I used it for black pearl peppers and it was fabulous! Hope this is what you were asking. Don

I never checked. I have it for herb plants and they are very happy. It is on the warmer side

For 6500K i just purchased From Triangle Bulbs and im really happy with them Triangle Bulbs T30045-10-VA (10 pack) - F14T5/865 14-Watt Straight T5 Fluorescent Tube Light Bulb, Daylight, 10 Pack

My unit came with an Agrobrite 6400 K color temp T5 lamp. You can put in what ever you want. T5 bulbs are available in a variety of color temperatures.

2000k lower blue spectrum... if you are looking for the warm bulbs (red spectrum), I believe you have to look for 3000k (lumens I think you are looking for). They cost more than the regular ones this comes with. Just no matter what, always make sure proper wattage. Not worth risking fire.

I don't know about that...I don't think it would work, I use mine for air plants & they are thriving.

The 6500k is a measurement of LIGHT OUTPUT -- it has NOTHING to do with the temperature (F. or C.) of the bulb or the room it's in !! The 27-Watt-bulb can be touched with the Lamp "on" -- it won't burn anything or anyone.

Generally yes, although i guess it depends what you are growing. Personally i switch to t5 bulbs that are between 30,000 k - 35,000 k. The lights it comes with are good for vegetative growth.

HPS is 3700K (red/yellowish) and MH is 6500K (white/blueish) I believe. I could be wrong its from memory... But the MH is for VEG, and HPS is for flowering. :)

You'll get no good usable PAR light from those led panels. Check out the 250w cfl in 2700k for flowering 6400k for veg. Best and cheapest. If using led use black dog

Just to give an idea of what your asking, 4000 K is 6740 degrees F. So yea, I would say any lights you find will not get that hot considering it will kill you, your neighbors and more. Not sure where you pulled 4000 K from.

This bulb is a grow bulb. It has a kelvin rating of 6500 which is suitable for growing plants. I have use lesser quality bulbs from local hardware stores with the same kelvin rating, only with a lower wattage that have been ok. This bulb provides a higher output along with the daylight spectrum of light.

I would say the light is closer to 6500k (more blue than white). I found this annoying because even though I enjoy white light for daily tasks it is too white/blue for me to keep on during the night. It is also a lot brighter than I expected!

Hi Tim ~We have mostly regular plants and herbs, which seem to love this light, but my husband says he doesn't really think this is the right light for flowering plants. He thinks Dan's recommendation is the correct one. Good luck!

The color temp of the light is approximately 3000k so on the warmer side. Comparable to a Halogen light.

It seems to be about that. I use mine for my porch light and it has been working in temps as low as 40 below. I have a 60w equivalent also and it seem about right too. This has the soft white color so it has the incandescent color.

These are closer to daylight color temperature - I'd estimate around 4500-5000K. Very bright pure white. Not recommended if you are looking for that low of a color temperature.

use the mh... this bulb is more than capable... but Id go with a cheaper MH bulb for veg since light is less critical in the veg stage

My plants have been growing great! I am not growing moderate-high plants though. It's a very bright light.

These are 3000 kelvin color. If you do not understand that, please do yourself a favor and go to a local lighting store to see them in person. Any light that produces 3000 kelvin will look the same with varying degrees of intensity.And as others have said, they are not good for plants. You can buy LED growlights, but they are only good in that they use very little power. And it is probably better to get a HPS bulb and ballast than to even think of LEDs.

It's color temp is 2700 to 6500. It works ok as desk or reading lamp. For general therapeutic effect, I prefer nature bright sun touch plus. I have both

Baku, I'm not sure about your question...if your interest is photographic, 5500K refers to color temperature emission of essentially normal visual range... A 6500K color temperature will produce a shift to a cooler range of colors
